Surprising discovery about the application Preview

Most, if not all Mac users know what preview is. Thought to be a program to open and view images, including PDFs. However, as it turns out, it’s not just a default image viewer. It’s actually a lot more than that once you know how to use the program. (I’ve been a Mac user for 16 years, and there are always little surprises around the corner.)

Preview can be used to edit photos in these ways: color adjustment, light adjustment, resampling images, batch processes, smart lasso (background drop, or otherwise), and even soft proofing.
